Neural stem cells have a strong self-renew mechanism and it can transform after a little break. Neural stem cells have a long term survival, which mean that it has more probability of wrong copy than mature cells. These cells are formed glioma stem cells in the end. The genes who adjust neural stem cells can express in glioma stem cells, which hold out glioma stem cells from neural stem cells. There is another presume that glioma stem cells come from differentiated cells. Through the gene break of these cells, they can obtain characteristics of stem cells, then form glioma stem cells.

神经干细胞具有很强的自我更新机制，获得较少突变即有可能恶性转化，而且干细胞存活时间较长，这意味着干细胞比成熟细胞发生细胞复制的错误几率更大，因外界环境的刺激而发生突变的机会更多，最终形成脑胶质瘤干细胞，同时调节神经干细胞增殖和自我更新的基因在脑胶质瘤的脑胶质瘤干细胞中也表达，这也是支持神经干细胞是脑胶质瘤干细胞来源的；也有推测认为它可能起源于已分化的细胞，由这些细胞突变发生去分化得来，并通过基因突变而获得了干细胞自我更新的特性，从而形成脑胶质瘤干细胞。

The book provides reviews on many of the areas of stem cell, such as organ repair and regeneration; transcriptional regulation of blood stem cells; stem cells and tissue engineering; human fetal mesenchymal stem cells; gene-modified mesenchymal stem cells as cytoreagents for regenerative therapy ; pharmacological characterization of embryonic stem cell-derived cardiomyoctye cultures; adult stem cells in cardiac cellular transplantation; pancreas and liver regeneration and neogenesis; and stem cells and clinical application so on.

该书提供了干细胞许多领域的评论，例如器官修复和再生；血液干细胞的转录调控；干细胞和组织工程；人类胎儿间质干细胞；基因修饰的间质干细胞作为再生治疗的细胞试剂；胚胎干细胞来源的心脏肌细胞培养物的药理学特征；成熟干细胞在心脏细胞移植中的作用；胰腺和肝脏再生；以及干细胞及期临床应用等。

However, the transformation rate from dominant stem to overtopped stem and from overtopped stem to dominant stem were the lowest. The interconversion of classified stem would increase as the stand density and the rate of L. gmelinii was going up. The altitude that classified stem mainly concentrated was less than 1000m, slope was less than 25°, aspect was south slope, position was at middle and lower, soil depth less than 17cm. The rate of no interconversion was 66.7% among overtopped stem. It should cut the overtopped stem as intermediate cutting.

优势木转被压木和被压木转优势木的转换率最低；随着林分密度和林分中落叶松比例增加，分级木相互转换数也增多；分级木转换现象主要集中在海拔＜1000m、坡度＜25°、坡向为阳坡、坡位为中下、土壤厚度＞17cm的林分中；被压木中，无转换的占66.7%，抚育采伐时应考虑伐除这些被压木。

Multipotent stem cells：多能干细胞

一)干细胞(stem cell)的基本概念目前常用的干细胞分类方法有两种:一种是根据其分化潜能的宽窄将干细胞分为全能干细胞(totipotent stem cells)、三胚层多能干细胞(pluripotent stem cells)、单胚层多能干细胞(multipotent stem cells)和单能干细胞(mo

pluripotent stem cell：多能干细胞

ES细胞)和成体干细胞(somatic stem cell).第二种分类方法是根据干细胞的发育潜能分为三类:全能干细胞(totipotent stem cell,TSC),多能干细胞(pluripotent stem cell)和单能干细胞(unipotent stem cell).胚胎干细胞的发育等级较高,
